For all those who might want to take advantage of the services mentioned by OP, keep in mind that the whole story may not be true
Exactly. A brand new account suggesting a mixer that no one has ever heard of before? This screams of a scam to me.
I suspect anyone who tries to get greedy and use this "doubler" will find whatever funds they send immediately included in a CPFP with a very high fee.
So It was not just me, the moment I saw he shared the link I started to get suspicious
Newbie account, a way to make money with ease, a somewhat believable story, I'm willing to bet that whoever tries that mixer will see no coins coming to him.
And if people think that they can play this game and the 1 sat transaction gives them an edge be careful, the "mixer" might use a CPFP transaction with a higher fee that will get confirmed along with your deposit in the next block.
